I specialize exclusively in Java 21, Spring Boot 3, and PostgreSQL. My entire focus is on server-side architecture and fixing backend bottlenecks quickly with production-ready code.
What I Can Do For You:
- API Debugging: Fix CORS errors, 500 status codes, JSON parsing, and broken routing.
- Database Optimization: Resolve Hibernate/JPA mapping issues, fix N+1 queries, and tune PostgreSQL performance.
- Security & Auth: Implement stateless JWT authentication using Spring Security.
- Docker & DevOps: Write custom Dockerfiles and docker-compose.yml to containerize your backend.
- Custom Endpoints: Build clean, documented REST APIs for integrations.
Why Work With Me?
- Focused Specialist: 100% dedicated to Java/Spring Bootno generic web fluff.
- Clean Code: Well-documented, readable implementations that won't break your build.
- Fast Diagnosis: Clear root-cause identification and straightforward communication.

FAQ
Do you help with deployment?
If your application needs containerization, I can write a custom Dockerfile and docker-compose.yml script to ensure it runs smoothly on your Linux environment.
Will you provide documentation for the fixes or new endpoints?
Yes, I provide clean, well-documented code with clear comments so your frontend developers can seamlessly integrate the updated REST API.
Can you fix database performance or N+1 query issues?
Absolutely. I can optimize your Hibernate/JPA mappings and refine PostgreSQL queries to resolve N+1 bottlenecks.
What do you need from me to start fixing my API?
I need a brief description of the error, any relevant application logs (like your 500 error stack traces), and access to your codebase via GitHub or a zip file.
Do you only work with Java and Spring Boot?
Yes, I specialize exclusively in Java 21, Spring Boot 3, and PostgreSQL. By focusing strictly on this backend stack, I deliver secure, production-ready code rather than generic full-stack work.
